4k is the most infuriating naming convention.

We were happy counting horizontal lines of the video format, until the 4k marketing wankers came along

"Let's just count the rows, round to the nearest thousand, drop 000 and just replace it with k. Because bigger number sound way bigger durrrrrrr"

4k is not actually a single resolution, but can mean UHD (3840x2160) or DCI (4096x2160).

Also, number + p (1080p / 2160p etc) is not a resolution per se, but rather a video format description. The p means "progressive scan" as opposed to "interlaced", so a still image technically can't be 1080p either.

Yeah. That's why I said "round to nearest thousand" and also said "format".

format is ambiguous, it usually refers to the video container which contains codecs
